Kuhn, Thomas

"The young scientist must learn the old paradigm thoroughly before transcending it."

"Revolutionary science is prepared in the laboratories of normal science."

"The textbook makes science seem more rational than it actually is."

"Science advances when communities are willing to question their foundations."

"The paradigm is invisible precisely because it is everywhere."

"What counts as a successful prediction depends on one's theoretical commitments."

"The scientist who sees anomalies is often the one trained differently from the mainstream."

"Paradigm wars cannot be won by evidence alone; they are decided by conversion and time."

"The history of science is the history of successive paradigms, not of accumulating truth."

"Revolutionary periods are times of both destructive and creative chaos."

"We are all trapped in our paradigms; the question is whether we can recognize the cage."

"The scientist who cannot communicate within his paradigm cannot be part of his scientific community."

"Scientific progress is not progress toward an ultimate truth but progress within a framework."

"The anomaly becomes a crisis when enough members of the community acknowledge it."

"Old and new paradigms are not simply rivals; they are incommensurable ways of seeing the world."

"The puzzle-solver and the paradigm-shifter speak different languages about the same world."

"Normal science solves puzzles; revolutionary science redefines what counts as a puzzle."

"The most important discoveries often violate what we thought was well-established fact."

"Scientific communities maintain coherence through selective perception and interpretation."

"The transition from one paradigm to another is not a logical process but a conversion."

"We mistake our theoretical predictions for facts about the world itself."

"The crisis phase reveals that the paradigm is not a neutral representation of nature."

"Revolutionary science requires scientists willing to risk their reputations on new ideas."

"The scientist is not born but made through initiation into a paradigm."

"What seems obvious to us would have been invisible to scientists of previous eras."

"The paradigm determines not just answers but which questions are worth asking."

"Scientific revolutions are moments when the entire map must be redrawn."

"The anomaly is not a problem to be solved within the paradigm but a symptom of its inadequacy."

"We navigate by paradigms because without them we would see nothing at all."

"The history of science shows that certainty is always temporary."
